This is a tool that we use to quickly assess the spectral performance associated with various FEC/Modulation combinations. It assumes that to you have adequate power to close the link at these FEC/MOD combinations effecitvely creating a power equivalent bandwidth utilization estimate.
This analysis does not accomodate for power or gain in the system which you can easily overcome with antenna and RF Amplifier size. There are two calculators here so you can compare results against each other.
